Zuckerberg and wife to donate vast majority of their wealth

Mark Zuckerberg and his wife Priscilla Chan will give away 99 percent of their Facebook shares, or about $45 billion, to "advance human potential and promote equality," the Facebook CEO announced Tuesday in a letter addressed to their newborn daughter, Max.

In the lengthy letter, posted on Facebook, Zuckerberg said he wants his daughter to grow up in a better world, noting that this generation can do so much more and pledging him and his wife will do their part.

“As you begin the next generation of the Chan Zuckerberg family, we also begin the Chan Zuckerberg Initiative to join people across the world to advance human potential and promote equality for all children in the next generation,” he wrote. “Our initial areas of focus will be personalized learning, curing disease, connecting people and building strong communities.”

“We know this is a small contribution compared to all the resources and talents of those already working on these issues,” he continued. “But we want to do what we can, working alongside many others.”
